cardiac skeleton – (also, skeleton with the heart) strengthened connective tissue Situated in the atrioventricular septum; involves four rings that surround the openings between the atria and ventricles, and also the openings to your pulmonary trunk and aorta; the point of attachment with the heart valves.
annular ligament – intrinsic ligament in the elbow articular capsule that surrounds and supports the head in the radius within the proximal radioulnar joint.
caudate – nucleus deep from the cerebrum that is part from the basal nuclei; together with the putamen, it is an element from the striatum.
adrenaline – Major and many powerful catecholamine hormone secreted through the adrenal medulla in reaction to shorter-phrase anxiety.
anterior cranial fossa – shallowest and most anterior cranial fossa of your cranial foundation that extends through the frontal bone towards the lesser wing of the sphenoid bone.
central sulcus – surface area landmark with the cerebral cortex that marks the boundary amongst the frontal and parietal lobes.
Bainbridge reflex – (also, identified as atrial reflex) autonomic reflex that responds to extend receptors inside the atria that send impulses into the cardioaccelerator area to extend HR when venous movement in the atria increases.
cilia – compact appendage on specific cells formed by microtubules and modified for website movement of elements throughout the mobile surface.
Cells, one example is, Have a very cell membrane (also generally known as the plasma membrane) that keeps the intracellular setting—the fluids and organelles—independent in the extracellular atmosphere. Blood vessels keep blood within a closed circulatory program, and nerves and muscles are wrapped in connective tissue sheaths that separate them from bordering constructions.
The link of your ribs for the breastbone—the sternum—is in all circumstances a secondary a person, introduced about by the fairly pliable rib (costal) cartilages. The little joints among the ribs as well as the vertebrae permit a gliding movement of your ribs over the vertebrae for the duration of breathing as well as other functions. The movement is limited from the ligamentous attachments between ribs and vertebrae.

brachiocephalic vein – one among a pair of veins that kind from a fusion on the external and internal jugular veins as well as the subclavian vein; subclavian, external and internal jugulars, vertebral, and inside thoracic veins produce it; drains the upper thoracic region and flows to the outstanding vena cava.
electronic arteries – shaped human anatomy meaning in the superficial and deep palmar arches; source blood for the digits.
basement membrane – in epithelial tissue, a skinny layer of fibrous product that anchors the epithelial tissue into the fundamental connective tissue; produced up of your basal lamina and reticular lamina.
